Faced with safety issues related to models, major technology companies choose to proactively take responsibility and commit to self-improvement, rather than relying on government agencies to step in. In practice, this is a very positive signal. For a long time, relying on self-regulation within the industry itself has been an important tradition in the United States.

If this is not constrained, then one day in the future, even an ordinary person singing a song might face the situation of needing official pre-approval.
